The facial recognition community continues to speak in circles when ethics is the topic. Notable business-to-business tech analyst Gartner is the latest with indistinct advice that amounts to "Please use better judgment." A new post by Gartner analyst Frank Buytendijk advises, "The appropriate use of facial recognition technology depends on the prevailing culture, ethics, legislation and practices." People in public might as well be fish in a barrel analyzed for profit by machine vision. Vendors leave questions of ethics in the hands of buyers.

New York-based tech consultancy ABI Research has stated in a press release that, whilst biometric investment struggles, AI has been gaining traction. The reason, the firm explains, is a logical one: government regulations seeking to limit contact and cross-contamination have made biometric equipment unappealing to the tech market, whilst the need AI-powered automation to maintain business continuity is growing. Dimitrios Pavlakis, Digital Security Analyst at ABI, considers that the biometric sector's loss could reach approximately US$2bn, which could have significant implications for the public sector. "Fingerprint biometrics vendors are struggling to uphold the new stringent hygiene and infection control protocols. These regulations have been correctly introduced for the safety of users and personnel, but they have also affected sales in certain verticals," he said.

Starting September 2019 in the European Union, a large portion of online payments greater than €30 (currently about $35) will require multifactor authentication. Consumers will need to use two of three things to verify transactions: something they know, like a password; something they have, like a digital device, perhaps a USB token, that identifies them; or something they are: biometric data. Proofs based on physical characteristics, like fingerprints and faces, are slowly becoming more common. This legislation will likely cause them to surge. Most consumers using biometrics will likely do so on their phones, many of which already have technology that payment-service providers will use to verify payments--such as Apple Inc.'s Touch ID fingerprint sensors or Face ID facial-recognition software on its iPhones.
